User blog comment:Hayds126/Why does this game have so much grinding/@comment-30893072-20170703235808

You gotta do TONS of grinding because they give you a chance to train your pokemon facing gyms, and like you said, they have ridiculously high-leveled pokemons.

I played PBB just for getting lotteries and/or collect pokemons to fulfill pokedex. But seriously, the main reason the gym has high pokemon levels is because the time between the next gym update is really long, regarding the fact our pokemon gets getting stronger between those times.

Lando64000 made the gym harder so he don't made the same mistake to brimber gym. Lando made the cap for pokemon level 40 at that time, and he releases a lv 30 gym, thus making so much player easily sweep the gym.

so yeah, you can quit PBB, or maybe think about this :)
